is more than feelings, listen to Feiao EM5 Flat Headset

mentioned flat-head headphones, people who have been playing headphones for some years should return to the days of Walkman. At that time, with the popularity of Walkman, flat-head headphones accompanied a whole generation as their listening "companion. However, with the rise of "Houlang" in-ear headphones, flat-headed earplugs have long become a term with a sense of age. At present, there are not many brands selling flat-head headphones on the market, and new products in recent years are even rarer. Therefore, Feiao's introduction of a new flat-head earphone called EM5 really made us more curious. Because the attention of EM5 is not only the type of flat-head earphone itself, but also the design that is somewhat different from the flat-head earphone in our impression, and the pricing that is not cheap... Is Feiao launching such a product just for feelings? I don't think it's that simple.

on today's numerous in-ear headphones, we can see a variety of styling designs and various visual effects brought by different materials and processes. However, it is relatively uniform to retrieve the impression of flat headphones in our mind. Therefore, when you see Feiao EM5, you should have the same feeling as me-both the familiarity brought by retro modeling and the visual impact brought by modern material technology. Feiao introduced the fourth generation DLP 3D printing process and skin-friendly resin material on EM5, which have been previously applied to many of its medium and high-end headphones. The seamless cavity has a crystal clear texture that we have not felt on traditional flat headphones.

▲ EM5 uses high-transparency and skin-friendly materials and the fourth-generation printing process. If the inside of the cavity is visible, the visual effect is good.

flat head earphones has a complex structure, which easily leads to the problem of large volume of earphones. At the same time, due to the open wearing mode, the low frequency of traditional flat head earphones has the characteristic of a large amount of leakage. So this time Feiao adopted a special design on EM5-separate the flute tube. The final result is that we can see an independent extended element on the cavity of EM5. The integrated seamless shape is quite special in visual effect, completely out of the modeling frame of the traditional flat-head earphone. Design innovation not only brings about changes in shape, but also helps to achieve a more solid and deeper low-frequency effect.

In addition to the classic left blue and right red logo design, EM5 has 3 more dots on the earphone handle, which is convenient for users to blindly operate the earphones.

In addition to reforming and optimizing the traditional flute tube design of flat-head headphones, Feiao also made an article on the headset unit. Beryllium-plated diaphragm technology has been applied to many earphones by Feiao. This time, it uses a large diameter 14.2mm beryllium-plated composite diaphragm on EM5. Beryllium material has the characteristics of strong rigidity, high hardness and light weight, which can make the frequency response range wider and control the distortion better. With the design of independent flute tube, a targeted solution has been formed to the problems that traditional flat-head headphones cannot go down at low frequency and cannot go up at high frequency. At the same time, Feiao also improved the results of the EM5 horn unit. The long-stroke design adopted has a larger limited displacement than the conventional horn, which is helpful for reducing distortion and improving the low frequency effect.

, Feiao has always been quite generous with the standard accessories of its various products. To sum up, it is "complete variety, large quantity and good quality", of which earphone products are the most obvious. In addition to the earphone itself, the most direct aspect of sound quality is the earphone cable. Feiao has always had a good earphone line as standard on its own earphones, and this time it has adopted a high-purity pure silver earphone line on EM5. The high-purity sterling silver earphone line has better conductivity and can bring more delicate and pure sound analysis.

In addition, another feature of this earphone cable is that it adopts a replaceable plug design. In the past, most of Feiao's in-ear earphones were designed with detachable earphone cables, usually MMCX or double-pin connectors. This time Feiao changed the replaceable part to plugs, making a standard earphone cable It can meet the needs of connecting different interfaces. The plug of the earphone line adopts the design of rotary lock type replacement. When replacing, it can be easily removed by rotating the positioning point of the plug to "ON". When connecting, the positioning point on the plug is aligned with the positioning point on the earphone line socket. After inserting it, it can be locked by screwing to "OFF", which is very convenient.

EM5 includes 2.5mm, 3.5mm and 4.4mm each, that is to say, one line is enough to play with most devices. Feiao has introduced many earphone upgrade lines for sale separately. Among them, the pure silver earphone line with MMCX or double-pin interface costs 698 yuan, and there is only one plug. The standard earphone line plus plug for EM5 will only be more expensive if it is sold separately. From the grade of the standard earphone line, it is clear that Feiao did not hesitate to work on EM5.

▲ The standard high-purity sterling silver earphone line is matched with three rotary-locking replaceable plugs of 2.5mm/3.5mm/4.4mm. Feiao has taken into account the needs of connecting various equipment.

On other accessories, in addition to the leather storage box HB3 that we are already familiar with, EM5 standard sponge sleeves also have three types, namely low frequency, transparent and balanced, with 6 pairs each.

▲ Leather storage box HB3 is also a standard accessory, which is very convenient to carry and store.

▲ Feiao provides EM5 with three different tuning sponge covers as standard, including 6 pairs of low-frequency, transparent, and balanced ones. Users can use them according to the sound requirements of different scenarios.

first, let's talk about the feeling EM5 brings to me. Put a sponge sleeve on the earphone and put EM5 into the ear. For me, who is used to in-ear headphones, this is a more relaxed way to wear them. EM5 has a moderate ear shell size and the buffer space brought by the sponge sleeve, which has a good fit with the auricle and good wearing stability. Secondly, there is no sound guide tube that goes deep into the ear canal. The open wearing design makes the presence range brought by EM5 naturally smaller, making the wearing experience easier and suitable for users to listen to music for a long time. Of course, the wearing method determines that the passive noise reduction ability of EM5 is not too strong. During the audition, let's see how much help its special structural design and large diameter beryllium plated composite diaphragm will bring to low frequency and other sound quality performance.

if you can't wait to listen to EM5 immediately after unpacking, you may be somewhat disappointed, because it is not in the best condition at this time, and EM5 needs to be cooked for a while. After cooking the machine for 5 hours a day for a week, the EM5 state came out. After cooking, the sound of EM5 is relatively stable, the chassis is solid, the sound density is high, and the three frequencies have a trend of medium and low, but the high frequency is not weak, and the overall situation is relatively balanced. The reason why it gives people the feeling of low trend is that EM5 has outstanding low frequency performance. EM5 low-frequency capacity is sufficient, diving has a certain depth, the sense of quantity is large and the shape is not scattered, and it has a surging and solid sense of hearing.

in music dominated by drums, the listener can well capture the details and unique texture of drum skin vibration from EM5. The intermediate frequency vocal part of EM5 also has the unique delicate listening feeling of the moving circle unit. The singer's position is slightly forward, and the knot is clear and full. The sound is presented in a warm tone, with no lack of details but not in the ears of the listener. In terms of high-frequency expressiveness, EM5 is characterized by smoothness and smoothness. It may not be as bright as its own multi-action iron unit headphones, but it still remains at a certain transparent level. At the same time, the high-frequency burrs are suppressed very well, and the details are sufficient to restore the texture of instrumental music.

EM5 has a sound field performance that surpasses many in-ear headphones of the same price. When performing large-scale symphonies, EM5 can construct a space with clearer levels and positioning, with a certain distance in both horizontal and vertical directions. The listener can capture the sense of air conveyed in it, not stuffy or suffocating. On the front-end collocation, it is recommended that conditional users use it with a balanced interface. I used EM5 to audition under the 4.4mm balanced interface and 3.5mm single-ended interface at the same front end. The former has obviously improved in both the shaping of sound field and the performance of three frequencies.

, as a product approved in 2017 and belonging to the minority in the market, EM5 is undoubtedly a product starting from feelings. However, Feiao is finally presented to users, but it is an EM5 that is more than feelings. With the advancement of technology and materials, Feiao has more space and methods to solve its inherent shortcomings while retaining the characteristics of traditional flat-head headphones. Whether it is the structural innovation or the application of the unit, it is the upgrade and transformation of the flat-head earphone.

in terms of sound quality, EM5 is outstanding among the flat-headed earplugs that we can still buy at present. Even in the highly competitive market of the same price, in the face of many in-ear headphones, its excellent resolution and excellent medium and low frequency performance are enough to open up its own market. I prefer to understand feelings as an added value of EM5, and its own sound quality is worth considering by consumers who are buying headphones at this price.
